042V/ /Ff/ f Aug. 12, 1930. H. E. HAsTlNGs BACK`STRAP BUCKLE FOR HARNESS Filed Sept. 17, 1929 Patented Aug. 12, 1930 HORACE E. HASTINGS, F HENRY, TENNESSEE BACKSTRA? BUCKLE FOR- HARNESS Application led September 17, 1929.

r-his invention relates to improvements in buckles particularly a buckle for use in conection with harness.

The primary object of the present invention is to provide an improved back strap buckle by means of which the back strap may be securely gripped and having means associated there yith for connecting a trace chain thereto so that the chain will be held at the proper point on the harness and so also that a pull may be exerted on the chain from the back strap as well as from the point on the collar of the harness where it is ordinarily attached.

Another object of the invention is to provide an improved back strap buckle having the above enumerated features and so designed that it may be easily and quickly released for disengagement from the back strap and for the release of the trace chain attached thereto.v

Other objects and advantages of the invention will become apparent as the-description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specilication, with the understanding, however, that the invention is notconiined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or inodilications mark no material departure from the salient features of the invention as expressed in the appended claims herein.

l*n the drawings nigure 1 is a ViewY in side elevation of the back strap buckle showing the application thereto of a strap and trace chain;

Figure 2 is a central longitudinal sectional view through the buckle.

Referring more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral l indicates the back plate of the buckle embodying the present invention wiich plate is, as shown, preferably of elongated rectangular configuration and has formed on one face at each side and at one end the forwardly extending bosses 2 Serial No. 393,175.

between which is positioned a latch plate 3, pivot elements l being extended through the bosses and into the adjacent edges of the'latch plateB so tnat the same may be swung relative to the plate 1.

The inner face of the latch plate 3 has Vformed transversely thereof adjacent the top edge or trie edge adjacent the pivotpoint thereof7 therib 5 which is formed to provide a series of teeth 6. n

Formed transversely of and through the .plate 1 is a pair of slots one being located be- 13 is formed for the reception of the keeper bar 1l in the manner shown. Directly beneath the lip '12 the body plate 1 carries a shelf like body 13 against which the free end of the keeper bar 11 presses when the same is in operative position.

In the use of the present back strap buckle the strap,.a portion of which is here indicated by the numeral le is passed through theslots 7 and 8in the manner shown in Figure lso that a part overlies the face of the body plate and when the latch plate 3 is swung to a position substantially parallel with the back plate the teeth of the rib 5 will bite intothe strap and bind it securely against the body plate. After securing the buckle at the desired point on the back strap the chain trace of the harness in association with Which the buckle is used is extended across the plate 1 so that one of the links thereof, such for example as the link 15 has the tongue 12 extended therethrough after which the keeper bar 11 is passed through the aperture 13 of the tongue and acts to maintain the chain link in position thereon. y

From the foregoing description it will be readily appreciated that with the buckle of the character herein described adjustment of the same on the harness back strap may be easily and quickly made and also the trace will be held in the proper position thereby and in addition some of the strain normally carried by the collar to which the trace is attached may be transferred to the back strap through the medium oic the tongue and plate of the buckle to Which the trace is attached. The shelf like body 13 secured to the tace ot the buckle plate l acts to prevent the accidental displacement of the keeper bar ll in the event that some other body is moved upe Wardly across the face of the buckle, the lower part of the portion 13 being sloped upwardly and outwardly as shown to throw orf any body moving over the buckle in this manner.

Having thus described my invention, What I claim is l. A back strap buckle of the character described comprising a back plate, means carried by the plate for engaging a strap passing thereover and binding the same against the plate, a keeper member carried by the plate adapted to maintain a trace chain in connection therewith, and a latching pin loosely.

carried by the irst means for extension through the keeper longitudinally of the plate.

E2. A back strap biukle comprising a back plate, a pivoted latch plate mounted upon the back plate and having a toothed edge adapted to be moved into close proximity to the back plate for the engagement of a strap passing thereover, means carried by the back plate for engaging in the link of a trace chain, and means carried by the latch plate for engaging the trace chain carrying means to prevent disengagement of the chain therefrom, said latch plate carried means being pivotally attached thereto and shiftable longitudinally of the back pla-te upon the swinging of the latch plate to disengage the trace chain simultaneously With the disengagement of the back strap by the latch plate.

3. A back strap buckle comprising a plate having a pair of spaced transverse slots therethrough designed to receive a back stra-p for the arrangement of a portion thereof over the face of the plate, a pivotally mounted latching plate carried by the lirst mentioned plate adapted to secure the back strap thereagainst, a keeper bar swingingly carried by said latching plate, an apertured lip carried by th-e back plate adjacent said latch plate and adapted to receive said keeper bar, said lip being designed for extension through a trace chain link, and means for preventing accidental displacement of said keeper bar.

4. A back strap buckle comprising a plate having a pair of spaced transverse slots therethrough designed to receive a back strap for the arrangement of a portion thereoi1 over the fare of the plate, a pivotally mounted signature.
